Use DOM and DOMXPath instead of regex, you'll thank me for it:

// something useful:
function dumpDomNode ($node) {
    $temp = new DOMDocument();
    $temp->appendChild($node,true);
    return $temp->saveHTML();
}

$dom = new DOMDocument();
$dom->loadHTML($html_string);

$xpath-> new DOMXpath($dom);

$elements = $xpath->query("*/div/[@class='begin']");

foreach ($elements as $el) {
    echo dumpDomNode($el); // <-- or do something more useful with it
}

Trying this with regex will lead you down the path to insanity...
